Specification of Letters Patent. Patented NOV. 30, 1920.

Application filed June 21, 1920. Serial No; 390,530.

T 0 all whom it may-0011067 21.

Be it known that I, Emrnn F. BAGKER, a citizen of the United States,residing atDavenport, in the county of Scott and State of Iowa, haveinvented new and useful 1m provements in Geared Locomotives, ofwlnch thefollowing is a full, clear, and exact de scrlption. p

My invention relates to geared locomotives and particularly to the typereferred to in mypending application for Letters Patent of the UnitedStates filed September 22, 1919, Serial No. 325,347.

The object of my invention is to provide a three point support forthecrank-shaft of such a locomotive that will always insure the axis of thesame and of the axle of the drive-shaft remaining in perfect parallelismso that the gears connecting them will always he in perfect mesh,substantially as hereinafter described and as'illustrated in.

the drawings, in which Figure 1 is a plan view of a broken away portionof the supporting-frame of a loco motive showing my improvementsapplied.

.the hearings in the pedestals of said frame for the axle 7 of the,drivewheels 8, 8. These bearings and the pedestals of theside-framesinwhich they are mounted are the same as those now in extensive use anda detailed description thereof is deemed unnecessary.

At its center of length axle 7 has a broad faced gear 9 securely mountedthereon and this gear is engaged by a pinion 10 of corresponding breadththat is securely mounted upon a transverse crank-shaft. 12, whose axismust always be parallel to the axis of the axle. In order to accomplishthis result a housing consisting of an upper and lower section, 13, andlhis provided for said gears which is placed between the sides of thesupporting-frame. These sections preferably correspond in constructionand design and have their longitudinal edges 15 flanged and securedtogether by bolts and nuts 16, or

other suitable means. In vertical longitudinal section the housing is,preferably, pearshaped, and the larger end incloses the large gear onthe axle 7 and the smaller end incloses the pinion on the crank-shaft.This housing has bearings, that are made half in the longitudinal edgeof its upper section and half in the opposing edge of its lower section,for the axle to pass through, and has bearings in the sides of itssmaller end in which the crank-shaft is journaled.

. lt'will be observed that the drive-shaft supports the larger end ofthe housing whereas the smaller end supports the crank-shaft. The endsof the crank-shaft pass out through guide blocks 17 that are supportedand have a vertically sliding movement in suitable openings or pedestalsin the supporting frame, and the vertical edges of said blocks aregrooved and the edges of the pedestals entersaid grooves and retain theblock in position.

The smaller end of the housing is, preferably, made slightly wider thanthe rear portion and each section has a corresponding V-shaped frameconsisting of converging arms 20, 20, that project from each corner ofsaid end and meet a suitable distance from V the housing at a point inalinement with the center of width of the latter and mer e into I n a bse1n1spherical members 21, 21, which, when the sections of the housingare secured together. form a spherical journal or hearing ball. Ifdesired, the V-shaped frames can be reinforced by vertical struts 22 22that are made integral with the adjacent ends of the upper and lowersections and extend in alinement with the center of the width of thehousing to the crotch of said arms 20, 20,

The spherical journal. above referred to is ournaled between an upperand lower transverse cross-bar, 23 and 24, the opposing surfaces ofwhich, where they areengaged by said semi-spherical bearing, areconcaved sufficiently to retain and support the adjacent end of thehousing, and to permit the rear end of said housing to move up and downsynchronously with either or both. of the drive-wheels, and at the sametime carry and maintain the crank-shaft absolutely parallel with thedrive-axle at all times.

It is evident that the improvements hereinbefore described can be usedin conjunction with geared locomotives of various designs. I do not,therefore, desire to be confined to the specific construction of theparts of my invention as hereinbefore described of any locomotive towhich said improve v, H g

axle of the drive-wheels ournaled in said vious that they may be changedto meet the I requirements of the changes'in the design ments might beapplied without departing from the principle of my invention. v

What I claim as new is: i "1 '1. In a geared locomotive the combinationwith a locomotive supportingsframe, and

the axle of the drive-wheels thereof journaled in the side members ofsaid frame,.of

V a transverse crank-shaft which imparts its motion to said axle, gearsconnecting said axle and crank-shaft, and means. journaled at one, pointat one end and at two points on the axle that retains said crank-shaftin constant parallelism with said axle.

2. In a geared locomotive the combination with a locomotivesupporting-frame, the axle of the drive-wheel thereof, journaled in theside members of the same, of a trans-.

,verse crankshaft which imparts its motion to said axle,gears'connecting said axle and shaft, a gear housing therefor one end of,which is .;pi otally mounted upon saidaxle and which has, hearings inits other end through which said crank-shaft extends, means providedwith bearings for sald crank-shaft the end of which farthest from saidaxle has a'single journaling member, and a single bearing thereforsupported midway between the side members of said supporting-frame.

In a geared locomotive the combination with-a locomotivesupporting-frameand the axle of the drive-wheel thereof ournaled in the side members ofthe supporting-frame,

of a transverse crank-shaft which imparts its motion to said axle, agear housing one end of which is pivotally mounted at two points uponsaid axle and has bearings in its other end for said crank-shaft, aswiveled journaling device for supporting the oppositeend of-the saidgear housing, and a H bearing therefor supported midway between the sidemembers of said supportingframe.

a. In a geared locomotive the combination with the locomotivesupporting-frame, and

the axle of the drive-wheels thereof, journaled in the side members ofsaid support- 1ng-frame, of a crank-shaft, gearing mounted'on andconnecting said shaft and axle,

a housing inclosing said gearing and pivotally mounted at one end onsaid axle at two points, and a universal omtconneetmg thesupporting-frame, of a floating transverse crank-shaft, gears connectingthe same to said axle, @journaled in said supportingframe, ahousing' forsaid gears, a substantially il-shaped' member the ends of which areconnected to the end of the housing farthest from the axle, and a ballattachedto 7 the vertex of said member, and a bearing thereforin across-member of sald frame "thatis adapted to permit said crank-shaftto'moveparallel with said axle at all times.

In a geared locomotive the comblnation with the isupp'ortingsframethereof, and the axle of the drive-wheels journaled in thesupporting-frame, of a floatingl -transverse crank-shaft, gearsconnecting the'same tosaid axle, a housing for said gears which ismounted on said axle and has hearings in its sides in which the crankshaft' is journaled, a substantially V-sha'pedmember the ends'of whichare connected to the end of the housing farthest from said axle, a ballmade integral with-the vertex of said /member, and a stationary bearingmade integral with said supporting-frame in-which said ball isjournaled.

7. In a geared locomotive the combination with the supporting-framether'eof,and the axle" of the dri-veswheels the journals of which havebearings in the supportingme, of a floatingltransverse crankshaft,

gears connecting the same to said axle, a

housing for said gearszconsisting of anvupper and lower section one endof which is mounted on said axle and which has openings initssidesthroughfwhilch the crank- V shaft passes a substantiallyV-shaped member supporting the end farthest, from the axle, a ball mademtegral with the vertex of said membenand a statlonary bearing madeintegral with E-said supporting-frame' in c which said ball isjournaled.

In witness whereof, I. have hereunto set my hand and seal this1 5th dayof June,-
